Phantom itching.....

Have any of you "suffered" from constant itching where once there was a breast. For the past 39 hours, I've been itching inside my boob that's no longer there as well as on my belly where they did the tram flap surgery. All those nerve endings are having a freeforall and it's' driving me nuts. I'm about to take two benadryl and go to bed, hopfully to get some sleep, the sleep I didn't get last night. I've scratched myself raw...and that hurts too.
